Time-restricted eating does not impact sleep, mood, quality of life: Study

For adults with overweight or obesity, time-restricted eating (TRE) does not lead to significant changes in sleep, mood, or quality of life, regardless of the timing of the eating window, according to a study published online June 25 in JAMA Network Open.

Antonio Clavero-Jimeno, from the University of Granada in Spain, and colleagues conducted a prespecified secondary analysis of a parallel-group clinical trial involving men and women aged 30 to 60 years with overweight or obesity.

The 197 participants were randomly allocated to receive usual care (UC; a Mediterranean diet education program) alone or combined with one of three TRE schedules: an eight-hour eating window in the early part of the day (early TRE); the late part of the day (late TRE); or selected by the participant (self-selected TRE; 49, 49, 52, and 47 participants, respectively).

The researchers found that for sleep, mood, and quality of life, there were no significant differences observed between the early TRE and UC groups. Compared with the UC group, results were also nonsignificant for late TRE and self-selected TRE groups; results were also nonsignificant between TRE groups.

“TRE appeared to be a well-tolerated nutritional strategy for managing body weight without apparent adverse effects on overall sleep health and psychological well-being in both men and women regardless of the fasting-eating window implemented,” the authors write.
